#493 ctf drop/slowdown, and basics of fugitive/follower

[sjtsp2008]

Two sets, mostly independent, but overlapping in Player.java

- CTF
- Fugitive/Follower

CTF Changes
-----------

data/conf/items/capturetheflag.xml

move flag to token item class, flag subclass
add arrows

data/sprites/items/ammunition/fumble_arrow.png
data/sprites/items/ammunition/slowdown_arrow.png
data/sprites/items/ammunition/speedup_arrow.png

new place-holder images for types of arrows (copies of wooden_arrow)

data/sprites/items/token/flag.png

new place-holder image for flag (copy of teddy)

src/games/stendhal/client/actions

TagClientAction.java - implement /tag on client side (copied from /tell)
SlashActionRepository.java - register /tag handler

/src/games/stendhal/common/constants

Nature.java - define two new natures
(this can be undone when a Weapon subclass of Item can have an effect
on entities. or if we just hack and look at the ammunition name)

src/games/stendhal/server/actions/chat

TagAction.java (new) handle /tag <player> [effect]

ChatAction.java - register TagAction

src/games/stendha/server/entity

RPEntity.java

import CaptureTheFlagFlag - support hack for droppable items

add Nature damageType to onDamaged() - supports deciding if

onDamaged handles fumble and slowdown when arrows used as normal weapons

added a speedModifier - will scale baseSpeed every turn. used for slowdown/recover/speedup

new methods
getDroppables()
dropDroppableItem(Item)
onDamagedFumble(Entity attacker, int damage)
maybeDropDroppables(attacker) called by TagAction - roll dice, possibly drop droppable
changeSpeed(double percentChange)
maybeSlowDown(attacker) called by TagAction - roll dice, possibly slow entity down temporarily

src/games/stendha/server/core/rp

StendhalRPAction.java - call to defender.onDamaged includes damage type

src/games/stendha/server/entity/mapstuff/area

DamagingArea.java call to defender.onDamaged includes damage type

LifeDrainArea.java call to defender.onDamaged includes damage type

src/games/stendha/server/player

Player.java added recoverSpeed()

XXX FollowingNPC stuff bleeds in

tests/games/stendha/server/entity

RPEntityTest.java - update onDamaged signature in a test subclass of RPEntity

Fugitive/Follower Changes
-------------------------

for any of these changes to be tested, you must update a zone xml file.
see below for an example.

src/games/stendhal/server/entity/npc

FollowingSpeakerNPC.java (new)

subclass of SpeakerNPC that follows a leader

startFollowing(Player)
stopFollowing(Player)

leaderMovedTo(Player, Zone, x, y)

TODO: factor Follower out - sheep, pets, ...

FugitiveNPC.java (new)

subclass of FollowingSpeakerNPC

reacts to being hit.

designed to easily support different personalities (toughness, ...)

NPCAttrUtils.java (new) helpers for configuring npc from bag of attrs

Player.java (note: should probably move these changes to RPEntity.java)

addFollower(FollowingSpeakerNPC follower)

add to list of followers

removeFollower(follower)

notifyMoved(Zone, x, y)

notify all followers that entity has moved to new location

overrides applyMovement to fire notifyMoved

src/games/stendhal/server/mapes/semos/hostel/FugitiveNPCSetup.java (new)

placeholder for setting up the Fugitive NPC with specified set of attributes.

probably should be moved to a new package - has nothing to do with the
hostel ...

To test/try out the fugitive/follower:

- add the following to semos.xml, and restart server

<configurator class-name="games.stendhal.server.maps.semos.hostel.FugitiveNPCSetup">
<parameter name="name">Fugitive</parameter>
<parameter name="description">On the Lamb</parameter>
<parameter name="x">19</parameter>
<parameter name="y">31</parameter>
<parameter name="direction">LEFT</parameter>
<parameter name="entityClass">chefnpc</parameter>
<parameter name="level">3</parameter>
<parameter name="atk">10</parameter>
<parameter name="def">10</parameter>

<!-- something about heal rate? -->
<parameter name="initHP">100</parameter>
<parameter name="pain-threshold">80</parameter>
</configurator>

- go to fugitive and attack (with a light weapon)

- should say ow, and eventually "i give up"

- say "follow"

- walk around. fugitive should follow you
- can even walk across zones, but they will immediately warp to where
you are

- say "stay"

- walk around. the fugitive will stay where they are

sorry, i forgot instructions on testing flag, arrows:

Testing CTF flag and arrows

best with two players - the carrier and the defender

# as an admin

/summon flag

- player1 picks up flag (can only go in l or r hand)

- should see teddy bear in hand, and balloon in outfit

/summonat player2 bag bow
/summonat player2 bag 100 fumble arrow
/summonat player2 bag 100 slowdown arrow
/summonat player2 bag 100 speedup arrow

- player2 equips bow and fumble arrows

- player2 can either attack player 1, or can "/tag player1"

- /tag fires exactly one arrow
- i have not figure out how to show the attack animation

- note that player1 will not automatically drop the flag
- both attacker and defender roll d20, and if attacker wins, carrier drops

- player2 equips slowdown arrows

- player2 tags player1 several times, and then player1 tries walking - should be slower,
and gradually recover to normal speed

- details: one arrow, if it hits, slows the target down 10%.
- players recover speed at 1% per second after that

- speedup arrows are available too, partly for testing, but maybe as
part of game strategy
